Trac is distributed with a powerful command-line configuration tool. This tool can be used to configure and customize your Trac-installation to better fit your needs.

Some of those operations can also be performed via the Admin web interface, an updated version of the ​WebAdmin plugin now integrated within Trac (since version 0.11).

Usage

For nearly every trac-admin command, you'll need to specify the path to the TracEnvironment that you want to administer as the first argument, for example:

trac-admin /path/to/projenv wiki list

The only exception is for the help command, but even in this case if you omit the environment, you'll only get a very succinct list of commands (help and initenv), the same list you'd get when invoking trac-admin alone.
Also, trac-admin --version will tell you about the Trac version (e.g. 0.12) corresponding to the program.

If you want to get a comprehensive list of the available commands and sub-commands, you need to specify an existing environment:

trac-admin /path/to/projenv help

Some commands have a more detailed help, which you can access by specifying the command's name as a subcommand for help:

trac-admin /path/to/projenv help <command>

trac-admin <targetdir> initenv

This subcommand is very important as it's the one used to create a TracEnvironment in the specified <targetdir>. That directory must not exist prior to the call.

initenv [<projectname> <db> [<repostype> <repospath>]]
Create and initialize a new environment
If no arguments are given, then the required parameters are requested
interactively.
One or more optional arguments --inherit=PATH can be used to specify the
"[inherit] file" option at environment creation time, so that only the
options not already specified in one of the global configuration files are
written to the conf/trac.ini file of the newly created environment.
Relative paths are resolved relative to the "conf" directory of the new
environment.

It supports an extra --inherit option, which can be used to specify a global configuration file which can be used to share settings between several environments. You can also inherit from a shared configuration afterwards, by setting the [inherit] file option in the conf/trac.ini file in your newly created environment, but the advantage of specifying the inherited configuration file at environment creation time is that only the options not already specified in the global configuration file will be written in the created environment's conf/trac.ini file.
See TracIni#GlobalConfiguration.

Note that in version 0.11 of Trac, initenv lost an extra last argument <templatepath>, which was used in previous versions to point to the templates folder. If you are using the one-liner 'trac-admin /path/to/trac/ initenv <projectname> <db> <repostype> <repospath>' in the above and getting an error that reads 'Wrong number of arguments to initenv: 4', then this is because you're using a trac-admin script from an older version of Trac.

Interactive Mode

When passing the environment path as the only argument, trac-admin starts in interactive mode.
Commands can then be executed on the selected environment using the prompt, which offers tab-completion
(on non-Windows environments, and when the Python readline module is available) and automatic repetition of the last command issued.

Once you're in interactive mode, you can also get help on specific commands or subsets of commands:

For example, to get an explanation of the resync command, run:

> help resync

To get help on all the Wiki-related commands, run:

> help wiki

Full Command Reference

You'll find below the detailed help for all the commands available by default in trac-admin. Note that this may not match the list given by trac-admin <yourenv> help, as the commands pertaining to components disabled in that environment won't be available and conversely some plugins activated in the environment can add their own commands.

Set milestone complete date
The <completed> date must be specified in the "MM/dd/YY hh:mm:ss" or "YYYY-
MM-DDThh:mm:ss±hh:mm" (ISO 8601) format. Alternatively, "now" can be used
to set the completion date to the current time. To remove the completion
date from a milestone, specify an empty string ("").
milestone due <name> <due>
Set milestone due date
The <due> date must be specified in the "MM/dd/YY hh:mm:ss" or "YYYY-MM-
DDThh:mm:ss±hh:mm" (ISO 8601) format. Alternatively, "now" can be used to

repository resync <repos> [rev]
Re-synchronize trac with repositories
When [rev] is specified, only that revision is synchronized. Otherwise, the
complete revision history is synchronized. Note that this operation can
take a long time to complete. If synchronization gets interrupted, it can
be resumed later using the `sync` command.
To synchronize all repositories, specify "*" as the repository.
repository set <repos> <key> <value>
Set an attribute of a repository
The following keys are supported: alias, description, dir, hidden, name,
type, url
repository sync <repos> [rev]
Resume synchronization of repositories
It works like `resync`, except that it doesn't clear the already
synchronized changesets, so it's a better way to resume an interrupted
`resync`.
See `resync` help for detailed usage.

session add <sid[:0|1]> [name] [email]
Create a session for the given sid
Populates the name and email attributes for the given session. Adding a
suffix ':0' to the sid makes the session unauthenticated, and a suffix ':1'
makes it authenticated (the default if no suffix is specified).
session delete <sid[:0|1]> [...]
Delete the session of the specified sid
An sid suffix ':0' operates on an unauthenticated session with the given
sid, and a suffix ':1' on an authenticated session (the default).
Specifying the sid 'anonymous' will delete all anonymous sessions.
session list [sid[:0|1]] [...]
List the name and email for the given sids
Specifying the sid 'anonymous' lists all unauthenticated sessions, and
'authenticated' all authenticated sessions. '*' lists all sessions, and is
the default if no sids are given.
An sid suffix ':0' operates on an unauthenticated session with the given
sid, and a suffix ':1' on an authenticated session (the default).

DDThh:mm:ss±hh:mm" (ISO 8601) format. Alternatively, "now" can be used to
set the version date to the current time. To remove the date from a
version, specify an empty string ("").
wiki dump <directory> [page] [...]
Export wiki pages to files named by title
Individual wiki page names can be specified after the directory. A name
ending with a * means that all wiki pages starting with that prefix should
be dumped. If no name is specified, all wiki pages are dumped.
wiki export <page> [file]
Export wiki page to file or stdout
wiki import <page> [file]
Import wiki page from file or stdin

wiki rename <page> <new_name>
Rename wiki page
wiki replace <path> [...]
Replace the content of wiki pages from files (DANGEROUS!)
This command replaces the content of the last version of one or more wiki
pages with new content. The previous content is lost, and no new entry is
created in the page history. The metadata of the page (time, author) is not
changed either.
If a given path is a file, it is imported as a page with the name of the
file. If a path is a directory, all files in that directory are imported.
WARNING: This operation results in the loss of the previous content and
cannot be undone. It may be advisable to backup the current content using
"wiki dump" beforehand.
wiki upgrade
Upgrade default wiki pages to current version
